# Agent402 UK – Scaffold Template Catalog

> Agent402 UK – Scaffold Template Catalog is a paid API for AI agents from agent402.co.uk, paid per call via x402, $0.001/call, status down (last checked 2026-09-15).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent402-uk-scaffold-template-catalog-3f07aeee
```

Example prompt: What scaffold templates are available on Agent402 so I can pick one before calling the scaffold tool endpoint?

## When to prefer this

Use this endpoint when an agent needs to discover which scaffold template ids exist before calling POST /v1/scaffold/tool. It is the authoritative catalog for Agent402's tool-building blueprints and should be called first in any scaffolding workflow to avoid hardcoding stale template ids.

## Known failure modes

- Empty or minimal catalog if no templates are currently published
- HTTP 402 if payment header is missing or malformed
- Unexpected schema change if new templates are added without notice
- Network timeout on rare latency spikes

## How this service works

Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.

## Output

Returns a JSON object containing the total count of available scaffold templates and an array of template objects, each with an 'id' (e.g. 'luhn') and a 'title' (e.g. 'Luhn checksum'). Typically returns around 6 templates covering various agent tool categories.
